22 Claims." (01. zit-1 1) My invention relates to improvements in window-sill construction, having to do with details of the sill of a window casing and the associated parts for the purposeof providing a combination that will tend to reduce the liability of leakage of storm water, snow,- sleet,

and the like past the sill and into the interior structure, and the object of my improvement is I to produce .a formoffwindow-sill construction that while relatively simple andeconomical to produce, is efiicient in substantially preventing such leakage in the corner structures at the lateral ends of the sill.

In the, accompanying drawing:-

Figure 1 is a fragmentary front elevation showing one of the-corners of a Window casing as viewed from the outside and embodying .my invention. I

Fig. 2 is an 'end elevation of the same as viewed from one of the ends of the sill.

Fig. 3 is a similarview of the sill only that is shown in Fig. 2.

Fig. 4 is a plan view of the end portion of the sill,- with dotted lines indicating the locations in the completely assembled structure. r

Fig. 5 is a sectionalview across the sill an part of the side casing structure. a

My improved window-sill construction pertains to details of the sill 10 and the parts thatare associated therewith, particularly at' the lateral ends 11, one of which is shown in Fig. 1,

and of which parts, the front side casings 12 are I the ones that are involved in thechanged and improved details.

Considering the side casing 12 that is shown,

this is in the form of a vertically elongated board structure of appreciable width that is an element inthe outside finish of the window casing and that by its bottom end abuts against the opposed top face portion of the sill 10. Back of I blind stop'13 and the side jamb1'4 to the full extent of the" exposed outside construction, so

that the lateral endfac'e 15 of the side casing 12, which is generally exposedds spacedoutward-i casing 12, this may extend outwardly beyond the blind stop 13 and the side jamb 14, but is'cutoff so that the outer end face 17 thereof is spaced of the parts that are superimposed thereupon.

lybeyond said blind stop 13. In the case of the portion 16 of the sill 10 that is back of the side end face 15 0f side casing 12 and the end face 18 of the front body portion 19 of the sill 10. Thusthe end portion 11 of .the body 19 of the sill 10 projects outwardly laterally beyond the 5 end face 1'7 of the rear portion 16 of the si1l'10.' The rear face 20'of the sill end portion 11 is flush. with the rear f ace'2l of the side casing 12,

and the position thereof. is determined by the unusual condition as so far described and one that is importantin considering the'present invention, in that there is a departure fromthe usual form of-construction at andadjacent the junction of the bottom; endface of the side casing with the 'sill.

.Back of the side casing 12 outwardly laterally beyond the blind stop 13 is generally open space so that there is substantially no obstruction to leakage back of the rear face 21 'ofthe side casing 12, except for the portion of the sill that is not cut-away and which has a slight inclination upwardly and inwardly as usual. In order to block such leakage I provide along the rear edges of the end portionsll of the sill- 10 a watershed 23 in the form of a riser or ridge of appreciable width and height that operates as a dam to obstruct rain water and the like from being admitted to the 'space back of the side casing 12.

- Said watershed 23 hasan'inclined face 24, and

while provided for thepurpose described at the end portions 11 is as a convenience in construc-' tion carried along the entire structure of the sill 10 from end to end.

The inclined face 24 meets the usual top face 25 of the sill 10 at a corner 26 in the form of an obtuse-angle. l

The bottom endface of the side casing 12 is' shaped to fit the obtuse angle 26'that is formed by the faces 25-and 24 to which it is opposed and is defined by the faces27 and 28 that meet at the ;corner 29 at an obtuse angle. a

The extension of the watershed ridge 23 with its inclined top face 24 inwardly from the side casing 12 along the sill and across the open space between the two side casings involves special attention in the use of certain auxiliary devices, such as blinds and storm windows, which abut in face to face contact with the blind stops. The

side casings and, therefore,

tom rear corner and involves the use of ordinary tools.

In the construction shown, the blindstop and the outside casing overlap one another in face to face contact; the blind stop projects inwardly into the inside open space beyond the inner edge of the outside casing; and the outside casing projects laterally outwardly beyondthe blind stop, all of which is common. In Fig. 2 the side casing 12 and the blind stop 13 are shown in such face-to face contact, the respective faces being designated as 21 for the side casing and 22 for the blind stop. The face-to-face contact is shown in Fig. 4 along the line designated by the character 20, the latter being applied specifically to the rear face of the sill end portion or sill extension 11 at the front sill end.

The inclined watershed 23 extends in one inclined face from the front top face 25 of the sill body upwardly and rearwardly and meets the top face of .the rear portion of the'sillprecisely at the junction of the faces 21 and 22.

The bottom end of the side casing 12 is made to fit against the opposed sill portion and the form of an exposed and accessible corner. By my construction a watershed is provided at this corner, so that water reaching this corner is runoff. Water may reach this corner directly as falling rain or indirectly by running down the faces that define the corner. The shed is positive.

I claim as my invention: 7

1. Inwindow-sill construction; a side casing, a blind stop opposed to said casing and extending inwardly beyond so as to form therewith a vertically directed corner, a sill, the upper face of said sill being opposed to the bottom ends of said casing and blind stop, with a portion thereof in registration with said corner, and comprising a ridge that extends across said portion, and said ridge being in the form of a relatively deep or elongated plain incline that begins at the extreme rear of said corner so as to shed water from the walls of said corner, the bottom rear corner of said casing being opposed to and fitting said ridgeby a plain beveled edge.

2. In window-sill construction, a sill, a blind stop and a side casing projecting upwardly from said sill and meeting by the front face of the one andthe inside face of the other to form a weatherexposed corner, said sill being provided with a transversely directed ridge that extends underneath said side casing, and the upper face of said ridge being in the form of a plain fiat incline that'begins by its rear top edge flush with said front face of the blind stop and that is opposed by the rear bottom corner of the side casing, said rear bottom corner being cut-away to provide a correspondingly plain flat face to fit thereagainst, whereby storm water received by said weatherexposed corner will be delivered past the junction of the blind stop and the sill directly to said ridge face and shed outwardly over the sill.
